【考案の詳細な説明】 本考案は、複数条の苗を横方向に並列載置可能な苗のせ
台を有する複数条植え田植機に関する。[Detailed Description of the Invention] The present invention relates to a rice transplanter for planting multiple rows, which has a seedling stand on which multiple rows of seedlings can be placed in parallel in the horizontal direction.

この種、複数条植え田植機においては、苗のせ台が走行
機体から横外側方に大きく突出して実質的に横巾の大き
な車輛となるため、路上走行時や格納時に苗のせ台の横
外側部が他物と衝突する危険や不当に大きな格納スペー
スを要するなどの不都合がある。In this type of multi-row rice transplanter, the seedling tray protrudes laterally outwardly from the traveling body, essentially creating a vehicle with a large width. There are disadvantages such as the risk of collision with other objects and the need for unreasonably large storage space.

そのため、従来τは、路上走行や格納を安全に行なう手

合も植付は装置又は苗載せ部の脱着に多くの手間と労力
を要し、面倒なものであった。Therefore, conventional τ was used as a means to safely drive on the road and store, and for planting, the entire device including the seedling stand was removed from the traveling body, and then towed in a vertical position using auxiliary wheels. Alternatively, methods have been taken to remove the seedling resting part located on the outside of the seedling stand from the seedling resting part located adjacent to it on the inside, but in both of these cases, the planting is done by the device. Alternatively, it takes a lot of time and effort to attach and detach the seedling mounting part, which is troublesome.

切換え可能に構威しであることを一特徴とする。In view of the above-mentioned circumstances, the present invention is designed to quickly and easily create a safe driving mode on small hills suitable for road driving or storage by simply folding the seedling stand. The purpose is to separate the seedling resting part located at least on the outermost side of the seedling resting stand on which multiple rows of seedlings can be placed horizontally in parallel, and the seedling resting part located adjacent to the inside thereof. swinging around a fulcrum set at a relatively high position so that the tips of the parts protruding upward from the seedling mounting part contact each other from above and below in a horizontal or almost horizontal plane and overlap. One feature is that it can be switched between a folded position and an expanded position.

での安全な走行形態を迅速、容易に、かつ、少ない労力
で楽に現出し得るに至った。As a result, when driving on the road or storing, the seedling resting part located on the outside of the seedling resting table can be moved from the extended position in which it is horizontally parallel to the seedling resting part located adjacent to the inside of the stand. It has a simple rocking operation that allows you to switch to the folded position by stacking it on top of it, and the seedling leaf holders that protrude upward from the seedling resting part can be used to remove attachments and parts such as rods and seedling stoppers one by one, or Without changing the mounting position, it has become possible to quickly and easily create a safe running mode with a small amount of oil, suitable for on-road driving or storage, and with less effort.
